Product Description
Ingeniously mounted above the sand conveying belt, this dynamic machine is a marvel of engineering, transforming green sand into a loose, workable state post-mixing. It ensures a seamless and efficient production flow, serving as a linchpin in the automated sand processing ecosystem.
Specifically crafted for the green sand casting mechanized sand recycling production line, this state-of-the-art machine excels in loosening mixed wet sand and efficiently crushing old sand after separation. Seamlessly integrated with the dust removal pipeline, it ensures pristine operations. By addressing agglomeration of wet sand post-mixing and old sand at drop stations, it markedly enhances the air permeability of molding sand (>80cm³/min), elevating the surface quality of castings. As the cornerstone of the sand processing system, this revolutionary sand loosening machine is transforming modern foundry workshops with unmatched loosening capabilities, efficient crushing, and advanced dust removal features. Our comprehensive analysis reveals how this groundbreaking machine empowers foundries, achieving efficient regeneration and pristine sand resource production through technological innovation, adaptability, environmental efficiency, and intelligent control.
1. Process pain points and technological innovation
Addressing the inherent challenges of compaction in wet sand (3-5% moisture) post-mixing and the critical need for crushing old sand embedded with core bone and iron impurities, this innovative loose sand machine achieves groundbreaking advancements with its dual-mode crushing structure and modular design:
Wet sand loosening mode:
Revolutionary rotary knife crushing system: Utilizing precision-engineered 304 stainless steel staggered blade groups (HRC55-60 hardness), this system skillfully slices through sand blocks at an impressive 1200r/min, with a processing capacity of 60t/h. The resulting loosened molding sand achieves a bulk density of ≤1.4g/cm³, significantly enhancing air permeability by an outstanding 40%.
Dynamic screening module: Incorporates a sophisticated built-in Φ8mm aperture grid that synchronously separates unbroken large particles (return rate <2%), ensuring that molding sand entering the conveyor belt is uniformly consistent (particle size standard deviation <0.15mm).
Old sand crushing mode:
Hammer impact mechanism: Equipped with high manganese steel hammer heads (impact toughness ≥120J/cm²), it expertly crushes old sand masses embedded with iron beans (diameter ≤20mm), achieving a crushing efficiency of 45t/h and an iron impurity separation rate exceeding an impressive 98%.
Magnetic pre-separation: A potent permanent magnetic roller (magnetic induction strength ≥1500Gs) is strategically positioned to pre-emptively extract ferromagnetic impurities, effectively diminishing hammer head wear by a significant 70%.
Intelligent switching technology:
Effortlessly enabling one-button transitions between wet sand and old sand processing modes via PLC control, with conversion times under a swift 3 minutes. This flexibility is ideal for both intermittent and continuous production line configurations.
2. Integrated solution for foundry sand processing line
The harmonious collaboration between the loose sand machine, conveyor belt, and dust removal system creates an efficient, cohesive sand processing ecosystem:
Space optimization design:
Brilliantly adopting an inverted installation structure, it commands a position above the B=800-1400mm belt conveyor, with a net height ≤1.2m, economizing an impressive 30% of vertical workshop space.
The precision-engineered standard design of inlet and outlet flanges (ISO 5211) ensures flawless, seamless connectivity with the sand mixer and old sand screening machine (connection error ±2mm).
Easy maintenance:
The innovative quick-detachable cutter head and hammer bracket design enable tool replacements in under 20 minutes, ensuring minimal downtime and sustained productivity.
Gas spring-assisted observation windows and inspection doors offer ease for solo maintenance tasks, streamlining daily upkeep with unmatched efficiency.
3. Core advantages and economic benefits
The loose sand machine redefines foundry sand processing standards through groundbreaking material innovation and intelligent control, offering unprecedented efficiency and operational excellence:
Wear-resistant and long-lasting design:
Experience unparalleled longevity and endurance with our state-of-the-art blade technology. The surface is meticulously enhanced using a sophisticated laser-clad tungsten carbide coating, varying in thickness from 0.3 to 0.5mm. This advanced treatment not only fortifies the blade but also extends its lifespan by an extraordinary four times compared to ordinary blades. This innovation ensures your operations remain seamless and uninterrupted, delivering superior performance.
Step into the future of effortless maintenance with our replaceable box lining, expertly crafted from ARQ wear-resistant steel plate with a remarkable hardness of HB450. This revolutionary feature dramatically slashes your annual maintenance expenses by an astounding 65%, allowing you to allocate resources more efficiently while maintaining peak performance and reliability.
Advanced Energy Consumption Optimization:
Embrace cutting-edge efficiency with our 55kW permanent magnet synchronous motor, ingeniously combined with a variable frequency drive system. This dynamic duo achieves an impressive 25% reduction in electricity consumption when compared to conventional asynchronous motors, ensuring a greener and more cost-effective operation that aligns with modern sustainability goals.
Our groundbreaking system redefines energy efficiency, consuming just ≤0.8kW·h to crush a ton of molding sand. This represents a significant 40% decrease in power usage compared to the traditional, energy-intensive roller crushers. Experience a remarkable reduction in energy costs while enhancing your production capabilities.
Superior Quality Enhancement Statistics:
Harness the power of precision engineering with our innovative system, achieving a compaction rate fluctuation of loosened sand at a mere ≤2%. This precision is further enhanced by a remarkable reduction in the porosity defect rate of castings, plummeting from 3.8% to an exceptional 0.5%. Elevate your production quality and reliability with these outstanding metrics.
Achieve unprecedented sustainability with an impressive old sand recycling rate elevated to 95%. This not only significantly reduces the addition of new sand by 60% but also marks a major stride towards eco-friendly industry practices. Embrace this leap forward in sustainable operations, reflecting a commitment to environmental responsibility and resource efficiency.
